The October demonstrations were centered in France and Italy, with echoes in Switzerland, Belgium, Spain, Portugal, and Scandinavia. Concerned for the moment with other matters, the German Communist Party did not participate. In Paris, even before the end of September various committees for action had met. Eight thousand militants filled the Salle Wagram and, on leaving, sang the “Internationale” while from a doorway someone lobbed a grenade at the drawn-up police, wounding several of them. The American Embassy was deluged with letters and telegrams. On October 19 a grenade, wrapped with sinister humor in a copy of the Royalist _Action Française_, was sent through the mail to the new American ambassador, Myron T. Herrick. The valet who opened the package set off the fuse but managed to throw it into a bathroom, where it went off, wounding him slightly and demolishing the room. On the twenty-fourth, ten thousand police and eighteen thousand troops had to be called out to hold back the vast crowd demonstrating before the American Embassy. The wave spread across Europe. In Switzerland the Communists organized demonstrations in Zurich, Basle, and Geneva. In St. Gall a letter to the American Consulate protesting the judicial murder of “Sachi” and Vanzetti was signed by Communists, syndicalists, socialists, and trade unionists. Amsterdam workers held a protest meeting, as did the Dutch Free Thinkers. Communists marched in the streets of The Hague, Brussels, Liége, Stockholm, and Copenhagen. The American ambassador in Madrid was threatened with assassination. In Lisbon a bomb was exploded in the vestibule of the consulate-general shortly after a letter had been placed under the door demanding the release of the “Brockton anarchists.” Medical students of Portugal’s National College struck for a day to show their sympathy. Although a demonstration by English Communists before the American Embassy fizzled out in a London rain, the Party’s Tooting branch forwarded its objections in a letter to the ambassador. A polite communication was sent to Washington by the Communist Party of Ireland.
